Preferably, the sealing module further comprises a plurality of gaskets, and the gaskets are arranged between the screws and the fixing holes in a matched mode.
According to the scheme, the gaskets can improve the tightness of the screws, so that the sealing effect is improved, and the safety is improved.
One preferred scheme is, the shaft hub both sides all are provided with the water conservancy diversion piece, the screw is spacing to be set up water conservancy diversion piece is inboard.
According to the scheme, the streamline structure of the flow guide block can well improve the water flow speed in the side pushing process, so that the power loss of the propeller during rotation is reduced, and the side pushing effect is improved.
One preferred scheme is, the axle hub both sides all are provided with waterproof axle sleeve, the screw adaptation sets up waterproof axle sleeve with between the water conservancy diversion piece.
By the above scheme, waterproof axle sleeve has increased the gas tightness of shaft hub prevents that the shaft hub from intaking, has improved the utility model discloses a security.
